Description

TECHNICAL FIELD The present invention relates to a gutter member, a gutter plate, a foundation block for installing a boundary block having a weed-proof function, a boundary structure of a paved road having a grass-proof function, and a concrete block set.

When providing paved roads such as paved roads and sidewalks, boundary blocks that form curbs are provided at the boundaries of the paved roads. Although there are various methods of installing the boundary block, the method of fixing the boundary block on a concrete structure such as a foundation member for installing the boundary block or a plate-shaped gutter (a gutter plate) is the mainstream.
There is a boundary block described in Patent Document 1 as a boundary block intended for weed control. This boundary block has a notch at the corner of the upper end on the sidewalk side, and the asphalt pavement of the sidewalk is overlapped and joined so as to cover this notch, thereby suppressing the growth of weeds invading from this joint part. It is a thing. This uses the property that the root does not grow against the direction of gravity, and is configured so that the root does not grow beyond the cut. In addition, there is a boundary block described in Patent Document 2 having a step portion for weed control.

In addition, a boundary structure having a weed-proof function using a conventional side groove member as shown in FIGS. 14, 15, 16, and 17 has been proposed. FIG. 14 shows a weed-preventing structure by a boundary block 601 attached to a conventional gutter member 600. The boundary block 601 has an acute-angled protrusion 602 with a wedge-shaped notch covered with a paving material that constitutes a sidewalk. Since the boundary block 601 having such acute-angled projections 602 has a special shape, the amount of circulation is small and the price tends to be expensive. Further, since the tip of the acute-angled projection 602 is sharp, it has a drawback that it is easily damaged.

The boundary block 603 shown in FIG. 15 has an acute-angled protrusion 604 with a wedge-shaped notch covered with the paving material that constitutes the sidewalk. Similarly, the boundary block 603 also has an acute-angled protrusion 604 and has a special shape, so that the amount of distribution is small and the price tends to be expensive. Further, the acute-angled protrusion 604 has a drawback that it is easily damaged. Furthermore, taking the semi-flat type, which is being adopted in urban areas in recent years as an example, it is standard to set the height of the sidewalk to be 50 mm higher than the roadway surface, but the height difference of the pedestrian crossing is up to 20 mm. Must be set to rub low. In this case, as shown in FIG. 15, since the boundary block itself has a thin structure, if the connecting portion of the acute-angled protrusion 604 has a thickness so as not to be broken, the condition of the notch shape to be a weed-preventing trap is satisfied. Unable to form a weed control trap.

The boundary block 605 shown in FIG. 16 has an acute-angled protrusion 606 with a wedge-shaped notch covered with the paving material that constitutes the sidewalk. Similarly, the boundary block 605 also has the acute-angled protrusion 606 and has a special shape, so that the flow amount is small and the price is likely to be expensive. Further, since the boundary block 605 has a low overall height, the portion provided with the acute-angled protrusion 606 is apt to be thin and has a drawback that it is very easily damaged. Note that the proposals of FIGS. 15 and 16 cannot be manufactured or used as actual products at present because of these drawbacks.

The boundary block 607 shown in FIG. 17 has an acute-angled protrusion 608 with a wedge-shaped notch covered with the paving material that constitutes the sidewalk. Similarly, the boundary block 605 has the acute-angled projection 608 and has a special shape, so that the amount of distribution is small and the price is likely to be expensive. Further, there is a drawback that the acute-angled projection 606 itself is easily damaged.

Hereinafter, modes for carrying out the invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing, as a cross-sectional view, an example of a boundary block that is generally in circulation. Such a boundary block is defined by a standard such as a JIS standard A type 100a, a JIS standard B type 100b, a JIS standard C type 100c having a slope on one side, and a standard 100d having a slope on both sides. There is. These standard boundary blocks are formed in a simple trapezoidal cross section with no irregularities on the surface. In the case of these standard boundary blocks, the width is 170 to 240 cm and the height is 200 to 300 cm. The present invention provides a boundary structure of a paved road having a weed-proof function, despite using a standard boundary block having such a simple trapezoidal cross section (including a rectangular cross section).

FIG. 2 shows a sectional view of the gutter member 1 having a substantially rectangular drainage pipe 3 therein. The external shape of the gutter member 1 is formed into a substantially rectangular shape. The gutter member 1 has a trapezoidal raised portion 5 provided on the upper surface portion of the upper wall 4 above the drainage pipe 3. The width of the upper surface of the raised portion 5 is formed to be 1/2 to 1/4 of the lateral width dimension of the side groove member 1, and is located at a position deviated to one side (paved road side) from the center of the side groove member 1. It is provided. In addition, the upper surface of the raised portion 5 corresponds to the height of the pavement surface when constructed, and is a portion that is arranged so as to be exposed on the ground surface. Although not shown in the figure, the raised portion 5 is provided with a hole penetrating the inside and the outside so that rainwater or the like can be taken into the drainage pipe 3 and drained.

The side surface 6 of the raised portion 5 on the paved road side is an inclined surface, and a notch-shaped recess 7 having a wedge-shaped cross-sectional shape is formed at the lower end of the side surface 6. Further, the concave portion 7 is provided at the upper corner portion of the gutter member 1, and is covered with the paving material installed. Since the boundary formed by the concave portion 7 and the pavement material that is constructed so as to be filled in the concave portion 7 has a V shape, even if seeds of weeds enter this portion, it reaches the lowest point. After that, the growth is suppressed due to the nature of the plant. The concave portion 7 forms a trap exhibiting such a weed-preventing function.

FIG. 3 is an external perspective view of the boundary structure in which the boundary block 100 is placed on the gutter member 1.
The side surface 8 on the sidewalk side, which is the side opposite to the paved road side (left side in the figure) of the raised portion 5, is an inclined surface, and the lower end 9 thereof is a flat mounting recess 10 on which the boundary block 100 is mounted. Touching. The sidewalk side of the mounting recess 10 is in contact with the lower end 15 of the side wall extension projection 14 protruding upward with the side wall surface 13 continuous from the side wall surface 12 of the side wall 11 of the side groove member 1. An inclined side wall surface 17 is formed in a portion extending from the lower end 15 of the side wall extension projection 14 to the top surface 16 of the side wall extension projection 14. The width between the side wall surface 13 and the side wall surface 17 is a flat surface having a constant width so that the top surface 16 does not form an edge shape. The width between the side wall surface 13 and the side wall surface 17 is prepared according to the bottom width of the boundary block 100 to be placed.

As shown in FIG. 2, the side wall surface 8 and the side wall surface 17 form, for example, inclined surfaces facing each other so as to narrow the width downward. This is intended as an optimal construction body so that the edge of the bottom surface of the boundary block 100 is in contact with one or both of the side wall surface 8 and the side wall surface 17, and the bottom surface of the boundary block 100 is the mounting recess 10. It is intended to be installed horizontally. At the time of construction, as shown in FIGS. 3 and 4, mortar is filled between the bottom surface of the boundary block 100 and the mounting recess 10, and the two are bonded together without any gap.
FIG. 3 is an explanatory view showing a state in which the boundary block 100 is placed on the side groove member 1, and the front end surface of the boundary block 100 is obliquely cut for the sake of explanation.

FIG. 4 is a cross-sectional view showing a state where the boundary block 100 is installed using the gutter member 1 at the boundary portion between the road 101 and the sidewalk 102 paved with a pavement material such as asphalt. FIG. 5 is an enlarged view of the portion A shown in FIG.
The gutter member 1 is embedded in the ground 103 at the boundary between the road 101 and the sidewalk 102. The surface of the ridge 5 is the same as or slightly lower than the surface of the road 101, and a hole is provided through the inside and outside to guide rainwater that has fallen on the road 101 to an internal drainage pipe. ing.

As shown in FIG. 4, the side wall extension protrusion 14 protruding upward along with the side surface continuous with the side wall 2 of the gutter member 1 is covered with a paving material such as asphalt forming the sidewalk 102. At this time, the pavement material is filled in the gap (space) 18 formed between the boundary block 100 and the side wall extension protrusion 14. This construction structure has an action of inhibiting the growth of weeds when the roots of the weeds invade the gap 105 formed at the contact portion between the boundary block 100 and the paving material forming the sidewalk 102.
When weeds enter the gap 105, their roots tend to extend along the direction of gravity. That is, the roots of weeds that have entered the gap 105 tend to extend toward the gutter member 1 while prying the gap. At this time, when the roots of the weeds reach the ground 103, the weeds do not stop growing because they acquire space, water, and nutrients, and the sidewalks 102 collapse or the walking becomes obstructed as the weeds grow.

However, in the case of the above-described combined structure of the gutter member 1 and the boundary block 100, it is possible to prevent the roots of weeds from reaching the ground 103. That is, even if the roots of the weeds open the gap 18 and extend downward to reach the ditch member 1 (contact portion 106) which is the lowest point, the weed roots form asphalt along the side wall surface 17 of the side wall extension protrusion 14 due to the nature of the plant. This is because the contact part does not open up and goes back to the side wall extension protrusion 14. That is, the pavement material filled in the gap (space) 18 and the side wall surface 17 of the side wall extension protrusion 14 serve as a trap to prevent the root from crossing over.

The side wall extension protrusions 14 are portions that protrude from the corners of the rectangular grooved gutter member 1, and thus are portions that easily collide with other concrete members during transportation and construction. For this reason, the side wall extension projections 14 are provided with a width (thickness) so that they are not easily broken and disappear even when an impact such as a collision with another side groove member or a boundary block is provided, and the strength thereof is increased.

Further, the angle θ formed by the bottom surface of the mounting recess 10 and the side wall surface 17 of the side wall extension protrusion 14 in contact with the bottom surface is preferably 60 degrees or less. In addition, if it becomes too gentle, the root cannot be turned upward. Therefore, in actual products, the angle θ is often designed to be about 20 to 45 degrees.
Further, in the case of the side groove member 1 having a total width of approximately 420 to 520 mm, the height Y of the side wall extension protrusion 14 is approximately 30 mm.

FIG. 6 is an explanatory diagram relating to another embodiment of the present invention. The gutter member 20, like the gutter member 1 described above, is a concrete conduit component member formed in a rectangular outer shape having a drainage conduit therein. In the description of the side groove member 20, the same components as those of the side groove member 1 are designated by the same reference numerals and the description thereof will be omitted.
Like the side groove member 1, the upper surface of the side groove member 20 has a trapezoidal raised portion 5 on the upper surface portion of the upper wall 4. The width of the upper surface of the raised portion 5 in this example is formed to be about 1/4 of the lateral width dimension of the gutter member 20, and is provided at a position deviated to one side (paved road side) from the center. In addition, the upper surface of the raised portion 5 corresponds to the height of the pavement surface when constructed, and is a portion that is arranged so as to be exposed on the ground surface.

The gutter member 20 is provided with a flat mounting recess 21 on which the boundary block 100 is mounted on the sidewalk side of the raised portion 5. Further, a raised portion 22 that forms the side wall surface 17 of the mounting recess 21 is provided on the sidewalk side of the mounting recess 21. The raised portion 22 is a portion that is raised upward along with the side wall surface 13 that is continuous from the side wall surface 12 of the side wall 11, and corresponds to the above-described side wall extension protrusion 14. As shown in the figure, the boundary block 100 is arranged and fixed in the mounting recess 21.

Even in the boundary structure formed by the combination of the gutter member 20 and the boundary block 100, it is possible to prevent the roots of the weeds invaded by the side wall surface 17 of the raised portion 22 from being crossed over and suppress the reproduction.

FIG. 7 is an explanatory diagram relating to another embodiment of the present invention. The gutter member 30 is, like the above-described gutter member 1, a conduit component member made of concrete and having a rectangular outer shape in which a drainage conduit is provided. In the description of the side groove member 30, the same components as those of the side groove member 1 are designated by the same reference numerals and the description thereof will be omitted.
The gutter member 30 is provided with a flat mounting recess 21 for mounting the boundary block 100 on the sidewalk side of the raised portion 5. Further, on the sidewalk side of the mounting recess 21, a protruding ridge 32 that forms the side wall surface 17 of the mounting recess 21 is provided.
The raised portion 32 is a portion that is raised upward along with the side wall surface 13 that is continuous from the side wall surface 12 of the side wall 11, and corresponds to the above-described side wall extension protrusion 14. The boundary block 100 is arranged and fixed in the mounting recess 21.

The point that the space between the boundary block 100 and the boundary block forms a trap that suppresses the growth of weed roots is the same as in each of the above-described examples, and this structure prevents the weeds from reproducing. The gutter member 30 has the same structure and operation as the previously operated gutter member 20, except that a trapezoidal raised portion 32 is provided on a part of the upper wall 4 on the sidewalk side.

FIG. 8 shows a case where a JIS standard A type boundary block 100a is mounted on the side groove member 1 described above, FIG. 9 shows a case where a JIS standard B type boundary block 100b is mounted, and FIG. 10 shows a case where a JIS standard C type boundary block 100c is mounted. It is a figure.
Each boundary block has a large amount of circulation and is generally used. The gutter member 1 and each of the gutter members 20 and 30 described above can exhibit a weed-preventing effect despite using a commonly used boundary block, which has a large amount of circulation.

FIG. 11: is explanatory drawing regarding the boundary structure of the pavement which has the grass-proof effect by the combination of the plate-shaped ditch board 200 and the boundary block 100.
The side surface 206 of the side groove plate 200 on the roadway side is an inclined surface, and a notch-shaped recess 207 having a wedge-shaped cross-sectional shape is formed at the lower end of the side surface 206. The gap between the concave portion 207 and the paving material 101 provided is a V-shape, and thus forms a trap that exhibits a weed-proof function when seeds of weeds enter the gap.

On the sidewalk side of the gutter plate 200, the side wall extension protrusions 14 similar to those of the above-mentioned gutter member 1 and a flat mounting recess 103 for mounting the boundary block 100 are provided. The gutter plate 200, when combined with the boundary block 100, provides a boundary structure between a roadway and a sidewalk having a weed-proof effect.

FIG. 12 is an explanatory diagram showing a combination of the embedded basic block 300 and the boundary block 100. The base block 300 is a concrete plate-shaped body, and has a mounting recess 301 for mounting the boundary block 100 at the center in the longitudinal direction. The depth of the mounting recess 301 is between 20 mm and 110 mm, and the most is about 30 mm. Side walls 302 having an angle of 0° to 60° are provided on both sides of the grooved mounting recess 301.
In this structure, even if the roots of weeds enter the gap between the boundary block 100 and the pavement material 303 such as asphalt, the roots extending downward are prevented from extending beyond the side wall surface 302. There is.

FIG. 13 shows a state in which a boundary block 400 having a low height is placed on the gutter member 1 having the above-described drainage pipe 3 therein, and the roadway 101 and the sidewalk 102 are divided with the boundary block 400 as a boundary.
